Specification of Letters Patent.

Patented June 23, 1908.

Application and May a, 190%. Serial no. 319,244.

To all whom it may concern:

Be it known that I, OTTO' HUBER HAsNn- DER, a citizen of the United States, and a resident of Scaford, in the county of Nassau and Satate of New York, have invented a new and Improved Acetylene-Gas Generator, of which the following is a full, clear, and exact descriotion. 4

The purpose of the invention is to provide a generator for acetylene gas, which will be compact, safe and durable and practically automatic in its action, and which will be an improvement upon the generator for which Letters Patent were granted to me May2, 1905, No. 788,901, to the extent that the entire machine is simplified in construction, and wherein the feed is rendered accurate, posi tive and sure, and wherein also the feed is of such detail construction and its operation is such that sticks and otherforeign matter is effectually prevented from passing into the generator with the charge of carbon' Another ur ose of the invention is to so construct tfie eed mechanism that the car'- hid will be prevented from sticking to the sides of the hopper, butwill be pulverized adjacent to and at the outlet for the hopper by the nested valves forming a portion of the feed mechanism, thus insuring a steady and uniform feed from the hopper to the genera tor at each operation of the feed mechanism.

A further purpose of the invention is to provide a float which will drop down to or enter the bottom of the generator, and. to provide effective and easily operated means for cleaning the generator from sediment, together with means for preventing tampering with such cleaning mechanism and likewise with the supply of carbid to the hopper.

The invent on COIISL ts in tie novel construction and combination of the several parts, as will be hereinafter fully set forth and pointed out in the claims.

Reference is to be had to the accompanyingdrawings forming a part of this specification, in which similar characters or reierence indicate corres )ondin r warts in all the fi ures. l s

modified form of the feed device, a portion of the hopper being also shown in section; and Fig. 5 is a bottom plan view of the cleaning shaft shown in Fig. 3, illustrating the position of the blades relatively to each other,

.L 1 and the shaft to the said olades.

A re resents the enerator B the hoeaer a P g r r and p the gasomete r of an acetylene machine, the gasometer consisting of the usual 5 body section a and bell section 0. The genera-tor A is provided with a conical top 10 and a more or less conical true bottom 11, the other bottom shown being generally omitted.

The true bottom 11 has an inclination from opening 12 is surrounded by. a reinforcingflanged neck 13, suitably secured to the outer face of the top 10 of the generator as shown in Fig. 1.

The hopperB is preferably given the form illustrated in Figs. 1 and 2, wherein the hop per consists of a lower conical section 15, an intermediate cylindrical section 14 and an upper truncated section 16. The lower section 15 of the hopper is attached to the neck 13 of the generator by passing bolts 18 through the of a sleeve 17 firmly and exteriorly secured to the said hopper as is also shown in Figs. 1 and 2. A closing plate 19 is provided at the upper central portion of the upper truncated section 16 of the hopper, and in this plate an inlet opening 20 is formed of suitable dimensions, surrounded by an upwardly extending exteriorly threaded collar 21, but the upper exterior portion of the said collar 21 is reduced and plain as is shown. in Fig. 1. V The collar 21 is adanted to have screwed thereon an interiorly tnreaded cover 22, and a cap 23 hlaving a suitable Washer is held to turn loosely in the cover 22, usually being supported therein by pins 24 extending from the cover below the lower edges of the ca as is also shown in Fig. 1, so that the cap :Nlll immediately engage with the upper end of the collar 21 the moment the cover is placed thereon, and the cover as it is screwed to lace on the collar will tend to press thecap mly and in a gas and air-tight manner in on the said collar. A hood 25 covers the co lar 21 and the cover 22 when in position on the said collar, and the said hood is hinged at its rear portionto the rear adjacent portion of 'fnthelower portion of the hop er, ex-

tending from ts central portion to W at may be termed the front side portion, so as to extend over the outlet 27 for the ho per B,

, engage with the slanting lower wall of the which outlet'is at the Tower pointe end of the hopper as shown in Fig. 1. The plate-26 is attachedto a box casing 29, the latter being supported bya suitablebraoket 28; and the salt box casing 29 is provided with a downwardly-extending circular neck 30, outwardly flared at its lower edge, and a ring 31 is se cured to the inner face of the lower conical section 15 of the hopper B, the inner edge of which ring is upwar ly and inwardly flared and is made to ap roach the flared portion of the neck 30 of t c said casing as is shown in Fig. 1. The openin between the out- Wardly flared portion of the casing 29 and the ring 31 is sufficiently large to permit the carbid to readily flow down to the outlet portion of the hopper and be directed to the sides thereof by theflared portions of:the casing 29, but said 0 ening is not suflicie'ntly large to permit stic s and other foreign matter to ass down even with finely reduced carbid. he carbid when placed in the hopper is deflected at the sides and-at the end portion of the plate 26 of the casing 29, by means ofa pyramidal plate 32, supported by the said pate26,asisshownini .1.

The feed device or mechanism controlling the outlet in the hopper B consists preferably, as is shown in Fi .1, of-three valves, namely, an outei tubu ar valve 33 0 en at the top and-at the bottom and of su cient diameter to move in the neck portion 30 of the casing 29, and of sufficient diameter to hopper B at a certain distance from the outlet 27, and this outer tubular valve 33 is provided. with an interior flange 34 adjacent to its u per edge. This valve 33 is pivotally attac 1ed to an arm 35 operating within the casing 29, and secured to a shaft 36 which extends out through the hop er at the front of the same as is shown in ig. 2, the shaft being provided at its outer end with an angular arm 37 secured thereto for a purpose to be I hereinafter described. The second valve 38 of the feed mechanism" is also tubu lar and is open at its bottom, partially open at the top and provided between its ends with an interior. ,annular flange 39. When the inner tubular valve 38 is raised certaindistance it engages with the flange 34 of the outer valve 33. The inner valve 40 is a plug valve, the lug 41 whereof is straight or conical and 18 adapted normally to'enter and close the outlet aperture 27, while at the same time the surrounding tubular valves have bearmg at their lower edges on the carbid around the said outlet, serving in the action of these valves to pulverize the said carbid, and also to prevent it from sticking to thesides of the hopper. The stem of this inner valve 40 extends up through the openin surrounded by the flange 39 in the inner va ve, and through the opening at the upper end of the said inner tubular valve, and said stern likewise passes through the opening surrounded by the flange 34 in the outer tubular valve 33, and at its up or end the said. stem is provided with a hea The plug 41 is within the inner valve ust below its flange 39. In the operation 0 this feed mechanism, in lifting it to cause a discharge of carbidinto the generator, the shaft 36 is turned by a means to be hereinafter described, and the arm 35 is lifted, which carries up the outer tubular valve-33. As this valve rises its flange 34 engages with the head of the valve 40 and raises said valve from its seat at the outlet 27, and the plug 41 of the said -valve 40 as the valve rises, in its turn engages with the flange 39 ofthe inner tubular valve and carries that 'valve upward, so that all the valves travel upward when carbid is to be released, but they move one after the other, and the movin influence is above the combined valves. in dropping,

the inner tubular valve closes first, ,the

valve 40 next, and the valve 33 last, and the action of the two tubular valves 33 and 38 in closing will cause a pulverization of the carbid below'them and likewise more or less agitation of the carbid around them, while the plug 41 completely closes the outlet aperture 27. The order of closing of said valves is just the reverse of the order of opening, and further with reference to said valves the outer one 33 is essentially an agitator, the valve 40 acts to close the opening in the hopper, and prevents moisture gain ing access to the carbid, while the intermediate or tubular valve 38 controls the feed,

but is assisted by the outer valve 33 sothat practically a double cut-off is secured.

The carbid is discharged automatically when gas is needed in the gasometer,,and therefore a lever 42 is employed, shown in Fig. 2, one end of which lever extends up to an engagement with a roller 43 at the top of the gasometer, while the opposite or front end portion of the lever 42 is usually pivoted .to the forked end of a crank arm 44, secured to a short shaft 45, journaled in proper bearings at the exterior of the hopper, and the inner or forwanlcxtremity of the lever 42, or that end ad'aoent to its bearing on the hopper, is 'rovided with a head 46, more or less pointe to engage with the angular arm 37 on the shaft36. Thus when the rear end of the lever 42 is pressed down by the downward movement of the bell of the gasoineter, the shaft 36 is rocked to carry the arm, 35 more or less upward to more or loss open the feed mechanism of the hopper. The short a s on the feed short 36 and thus permit the lee slit-zit 4.5 is mounted to turn so that the lever s in has swinging movement, enobli-n lever,

. i L .1. as will be hereinafter described, todisengzwe 1 ting the feeding mechanism to remain in inactive closed position, while the hopper is being filled, since it will then be unsil'ected by the rise or fall of the gasoineter.

Within the generator A at one side near the front u tube 47 is constructed (men at r 1 1 the top end at th bottom, and the water inlet pipe 18 for the generator is passed into said tube. The tube 47 is a guide tube for the flout 49, end the upper end of the guide a tube extends out throu h the top portion .9 a r of the said generator as is shown in both Figs. 1 end. 2. The float 49 operates a disk valve 50, which is mounted to turn in the reinforced neck of the generator, and when 25 the said Volvo is in its normal position, that shown in F 1, the cerbid in passing from the hopper to the generator will not be interfered with; but at other times the valve 50 is in s horizontal osition and when in such 39 position receives t e charge of cox-bid, should one be given, until a suitable time arrives to discharge it into the generator. The float 49 is provided st its upperportion with on i interior pertition 49*, extending down a slightldistunce from its top as shown in Fig.

1; end in connection with said flout two mam pipes at and a are provided and a brsnch pipe ab The pipe a extends from the bottom of the generator, being above the 4 Water line, ondds carried down through the enerstor and niade to connect with. the

ower water seal 72 in't'he gzlsozneter. The

\ other insin pipe a extends up into the iioet to s point at one side of its partition, and said pipe u is then carried downward and is connected'with the lower compartment in the esometer formed by a partition 70. The

Y ranch pipe o extends from the main. pipe a and is carried beneath the guide tube 1 7 for the ilost 49 and then up into the float to a position at the op )osite side of the partition -19 to thet occupied by the upper end of the pipe or; In the operation of this construction, if the gas pressure is too severe in the gesonr s5 eter the gas will find its way down through the main pipe u, will pass up the branch pipe. 'o 'und will raise the can i), causing the valve 50 to close; and as the float rises sufficiently to carry its partition; 49 above the 50 upper ends of both thc pi es a and 0/, the

gas in the float will pass own through the pipes into the said lower chamber of the gasorneter and out through discharge pipe fi o connected with such chamber as shown inl rg l.

I desire it to be understood that the float 49 may be placed wholly within the generator it so desired. The valve 50 is brought to a receiving position when the water in the generator is below the proper level, but when the water reaches the proper level, which level is shown in Fig. the valve reverses and dumps-its load, or is carried out of the path of the ccrbid falling from the hopper. This valve 56 is provided with ii stem 51, extending out tin-(nigh the neck 13 of the generator, and the stem is usually provided with a T-head 52, the members oi" which head enter slots 53 and 5% in arms extended upward from the upper end of the float 49, as is illustrated best in Fig. 2. When the Host rises to its normal position its action is to turn the valve 50 to s discharging position; but when the [loot 49 drops down from its normal position it turns the said valve 50 to intercept the carbid; other means, however, may be provided for this purpose. A substontiall conical de-- fleeting plate 56 is located within the genera tor at its upper porti on, in order to confine the. csrbid within certain points, and to coinpel all the dust to dissolve as Well as the solid particles oi 'cerbid, thus preventing choking of the burners; and it also prevents a collection of dust below the feed.

In Figs. 3 snd5 l have illustrated means for cleaning the generator, and to that end I employ a tube 57 open at the top and bottom. This tube passes down through the top 10 of the generator with a downward and rearward inclination, but stops short of the conical bot-torn 11. A shaft- 58 extends the length of the said tube 57 and is protected thereby, and the upper outer end of the shaft is provided with ohendle 59, While the inner end of said shaft 58 is mounted to turn in a bearing 60 secured to the central portion oi the said bottom 11. Opposing blades 61 are securedby suitable hubs to the lower end of the shaft 58, and these blades, which are given a propeller twist in opposite directions as is shown in Fig. 5, travel over the bottom 11 quite close to its inner face, and serve to clean the bottom without actually scraping it and to set up a violent ,egitetion in the liquid in the generator. This agitation is further brought about by the addition of agitating arms 62, which are curved in opposite directions snd are oppositely located above the blades 61, the propeller-like blades 61 end thecurverl agitating arms 62 being at right angles to each other. The water and the slush are d awn oil from the bottom portion of the generator through a suitable olitoke faucet 63, preferably located. at the front, the plug 64 whereof is operated by connection With s rod 65, and said rod extends up through" one or more guides 66 to a point at or near the upper end of the tube 57. The

Water inlet tube 48 for the generator is carried around to the front of the machine up.

. 63, hinged at one end to the top of the generator, the opposite end having connection with the plug 64 of a valve 65 located in a relief or discharge pipe 66 leading into the dome of the generator, and this plate 63 19 is provided with a handle 67 connected by a chain 68 with the hood 25 of the generator.

Any approved means may be employed for locking the handle 67 in its lower position,

and at such time the valve in the relief or.

discharge pipe 66 is closed and the hood y is also held closed so that the contents of the hopper can not be tampered with. When the cover is raised the valve 64: is opened, and the gas in the generator will escape into the discharge pipe 66 of the gasometer with which it is connected as is shown in Fig. 1,

thus permitting the gas to escape from the generator and enabling the hopperto be conveniently filled.

25 .When the cover-plate 63 is o ened it uncovers the pipe 48, ermitting t e generator tobe supplied witl i water, and it likewise enables the outlet valve 63 of the generator to be opened. It also causes the chain 68 to sl'acken, so that the hood 25 of the hopper can be drawn back to fill the hopper or to inspect it. A short length of chain 68 is attached to the chain 68 and to the arm 44 so that when the hood 25 is removed to fill the draw the lever 42 back from engagement with the latch head 37,,thus when the valve 65 is open the motion of the gasoineter ceases to affectv the feed of the carbid. It may bev here remarked that gas can only escape through the pipe 66 when the valve 65 is open, which as stated is when the hopper is'to be charged. 7

The gas supply ipe 69 for the generator, and which may a so serve as an overflow ipe, enters the body 0 of the gasometer (J at its bottom portion. The body 0 of the gasometer may be provided with a horizontal partition 70, whereby to provide an upper water seal 71 for the bell c of the gasometer I and the second water seal 72 in the lower por-' tion of the body of the said gasometer. A

as-receiving ox 73 is sup l oweinwater seal, as shown in li 1, the hot- 55 tom of the box being open anc its bottom edge being provided wit 1 serrations 7 4. In this box 73 a smaller box 75 is supported, at-

tached to the discharge end of the gas supply pipe 69, which pipe also asses through the 0! er receiving box 73. he serrations 74 at the lower end of the receiving box 73 are provided so that the gas will offer-the best possi- 'ble resistance to the water seal 72; and the lower edge of the inner and'smaller box 75 is provided with similar serrations 7 6 in order hopper the said short length of chain will orted in this that the discharge of gas from the smaller into the larger box will be as slow as possible;

A pipe 77 is introduced into the larger re: ceiving box 73 at the top, and this ipe ex- H tends. through the partition in t e body 3 of the gasometer up to a point beyond the level oi 'the upper water seal 71 In this manner the gas enters the bell, and the gas passes out from the bell through a pipe'78 which is ractically a duplicate of thepipe 77, but t ,e lower end of the pipe 78 is irn-j mersed in the water seal 72, and a branch pipe 7 9 is provided to carry the gas from the pipe 7 8 to a purifier 80 of anyapprov'ed type.

11 order to prevent danger of the gas 80 ometer being overloaded I employ a pipe 81 intermediate of the pipes 7 7 and 78, which intermediate pi e 81 extends'through and below the artition 70; and a second pipe 82, closed at its top and secured to the upper 35 portion of the bell'of the gasorneter, is made to telescope the tube 81, and the telescoping tube 82 is provided with a slot 83therein between its ends. When the bell rises'suiiiciently to bring the'opening 88 in the tube 82 9Q" above the upper end of the ntermediate pipe 81, the overplus gas will pass out through the bottom of the-tube 81 into the lower chamber of the body, and out through the discharge ipe 66. 5

In Fig. 4 l have illustrated a slightly v modified or simpler form of l eed'deviee, and one which is es ecially adapted to he used in connection witi large-grained carbid; The. hop er B is the same as that heretofore descri ed, being provided with the same char" acter of outlet opening 27. The feed device, however, consists of an outer'circular valve 84, rovided with a chamber 85 therein exten in from a point near its u per end throng its lower end, so that the ower end of the valve is open and its upper end is closed, except that a central opening 86 is made therein. The outer valve 84% is connected in any approved manner with the aforesaid arm 35 acting in. the ho per. The inner valve-87 is solid,.is of less ength than the length of the chamber 85 in theouter valve and has slidin movement in said chamber, being provided with a stem 86,

which extends out through the opening 86 in the outer valve and terminates in a head 89. Thus when the outer valve is raised, which is the'first tobe raised, it passes some distance up before it raises'the inner valve 87 to inno cover the outlet in the hopper, and on the return action of these two-valves the act one after the other upon the carbid w ich may have collected around or adjacent to the outlet 27, the inner valve 87 closing the said outlet while the outer valve rests upon the surrounding inner surfaceof the hopper.

It may be here remarked referring to the construction of the generator as illustrated in Fig. 1, that the connection between the cenearn as tral and annular gas spaces is brought about said central space, or within the space defined by the deflecting plate, forces the water in the body of the generator downward,

whereupon the gas is forced through the water and bubbles up into the annular space and is more or less purified in its passage 'from one space to the other.

Having thus described my invention, I claim as new, and desire to secure by Letters Patent, I
